永磁同步电机无速度传感器模糊滑模控制方法
Speed Sensorless Fuzzy Sliding Mode Control Method of Permanent Magnet Synchronous Motor
摘要
Abstract
Aiming at the problems of buffeting,large overshoot and slow response in the application of sliding mode control,an improved vector control system for permanent magnet synchronous motor(PMSM)is proposed.Firstly,a mathematical model of sliding mode observer(SMO)in synchronous rotating coordinate system is established,and saturation function is used as the sliding mode switching function.Secondly,according to the influence of sliding mode gain on system response speed and chattering phenomenon,a fuzzy sliding mode observer is designed to realize dynamic adjustment of sliding mode gain.In addition,introduce static control,improve the system response speed on the basis of improving the control effect of sliding mode control(SMC).Finally,in order to ensure the stability of the system,the Lyapunov stability criterion is used to analyze the system,and the feasibility of the method is verified by simulation.关键词
